<function>array_merge_recursive</function> merges the elements of
|
|
two or more arrays together so that the values of one are appended
|
|
to the end of the previous one. It returns the resulting array.
|
|
</para>
|
|
<para>
|
|
If the input arrays have the same string keys, then the values for
|
|
these keys are merged together into an array, and this is done
|
|
recursively, so that if one of the values is an array itself, the
|
|
function will merge it with a corresponding entry in another array
|
|
too. If, however, the arrays have the same numeric key, the later
|
|
value will not overwrite the original value, but will be appended.
